TH400 Intermediate Band

The TH400 Intermediate Band from TCI is a precision replacement friction component designed for builders and mechanics working on Turbo 400 transmissions. This band is crucial for controlling intermediate clutch pack engagement, ensuring proper shift timing, and preventing slippage under load. It is particularly beneficial for those restoring classic muscle cars or building high-performance street machines.

Manufactured with premium friction material bonded to a steel core, the TH400 Intermediate Band is engineered to withstand repeated engagement cycles without glazing or premature wear. The band wraps around the intermediate drum, applying controlled pressure to modulate power delivery during 1-2 and 2-3 upshifts. Proper adjustment is essential; too tight can cause harsh shifts and increased heat, while too loose can lead to slippage and power loss.

This intermediate band is ideal for transmission builders and DIY enthusiasts working on TH400 rebuilds or upgrades. It is compatible with various applications, but users should ensure it meets their specific vehicle requirements. Installation requires transmission removal, making it suitable for those with mechanical experience.
